Abstract

[Autom. eng. transl.] "Confined" environments, where the majority of the population spends between 80 and 90% of their time, are increasingly the subject of concern in relation to "indoor" risk factors. Among these, radon, the second leading cause of lung cancer, deserves special attention, especially in those environments, such as schools, where the stay is prolonged and those exposed are particularly fragile. This work, an integral part of a more complex integrated risk management approach to indoor air quality, reports the results of a radon monitoring activity within a sample of Italian schools in order to assess the exposure of teachers and students, while promoting the culture of prevention. The environmental diffusion of the Radon was evaluated through the use of an active 'Continuous Radon Monitor - 1028' type detector of the 'Sun Nuclear Corporation "in 7 Italian schools. The minimum monitoring period was 48 consecutive hours with frequency of continuous sampling Physicians in specialized training and prevention technicians of the Institute of Hygiene of the Catholic University of the Sacred Heart of Rome, after having recorded in a specific form the structural information relating to the building and the perception of the phenomenon by the residents, they placed the instrument at respiratory height (between 1 and 1.20 meters from the ground) in a room representative of the "worst case" of the school.The data were interpreted in accordance with current legislation (Legislative Decree 241/00) and are were elaborated through descriptive and inferential statistical analysis through the software: "Microsoft Excel 2011" and "Stata IC 9.2 for Mac". A total of 7 scs were monitored uole in 6 cities in 5 Italian regions. The average concentrations detected in our study [80.87 ± 72.4 Bq / m3] are in line with other epidemiological studies already conducted in Italy and, similarly to the latter, show significant differences between the various sampled schools, with values included between 0 Bq / m3 and 364.3 Bq / m3. Radon was significantly lower in the presence of students and staff who, with movement and ventilation induced by open doors and windows, reduced their concentrations in the environment. Therefore, although in our study the risk from exposure to indoor radon in the schools examined can be considered generally low for the personnel and the students, this is not due to a correct design or construction of the same, as to the 'involuntary' action of active ventilation o passive determined by the very presence of the exposed! Furthermore, the study highlighted a lack of awareness of the problems connected to indoor pollution, in particular related to radon, despite the considerable interest in deepening these issues both by the teaching staff and by the students. Therefore, in order to implement not only the 'empowerment' of the exposed subjects, but to induce a new 'reflection' on the problems related to Radon and to the need for new directives, technical standards and guidelines useful for an effective design both for structures that for materials used, the present study highlights the need for a thorough and widespread integrated and multidisciplinary prevention and the need for a 'consensus' within scientific societies still far from being fully realized.
